为使桩基计算工作简化,目前对“m”法及“K”法皆采用了无量纲系数,[2]～[3]前者的地基系数是假定随桩的入土深度成正比而按三角形分布如图1—(b)所示,后者则按折线形分布[4]如图1—(c)所示,但对地基系数为常数,即随桩的入土深度按矩形分布(图1—(a)]的单桩计算(以下简称“K”法,因地基系数用常数k表示)则多沿用初参数法。“K”法对嵌入岩层及固结的粘性土中的桩基以及其他地下结构
In order to simplify the calculation of pile foundation, both the “m” method and the “K” method are adopted non-dimensional coefficients. [2] ~ [3] The former foundation coefficient is assumed to be distributed in a triangle As shown in Fig.1- (b), the latter is distributed in a zigzag pattern [4] as shown in Fig.1- (c), but the coefficient of foundation is constant, that is, (K) method, because the coefficient of the foundation is represented by the constant k, the initial parameter method is used more than the K parameter. The “K” method is more effective for the pile foundation embedded in rock formations and consolidated cohesive soil and other Underground structure
